Definitions
- the invention relates to a system for generating electrical energy, in which a rod clamped at one end is made to vibrate and the vibrational movement is used to generate electrical energy.
- the rod clamped at one end forms a vibratory system that, when subjected to periodic loading, oscillates with an oscillation frequency and amplitude that depends on both the frequency of the periodic loading and the physical and geometric properties of the rod depend.
- each vibratory system also has its own so-called natural frequency, which is of essential importance if the vibratory system is loaded with a periodic load which has a frequency which exactly matches the natural frequency of the loaded system.
- the phenomenon of resonance takes place, which, as is known, causes a significant increase in the amplitude of the oscillation, which corresponds to considerable energy storage within the loaded system. If the energy storage becomes too large, the resonance can lead to a physical breakdown of the loaded system, so that in order to preserve the physical integrity of the loaded system, one usually prevents the resonance from taking place, i.e. the frequency values that are close to the value of the natural frequency are avoided.
- the object of the invention is to provide a system for generating electrical energy that is able to utilize the phenomenon of resonance in order to generate electrical energy.
- the document US 2019/0003448 A1 shows a system for generating electrical energy, in which the vibrational movements of the sea waves are used to generate a mechanical movement that can be transmitted to an alternator.
- this object is achieved when a system for generating electrical energy has the characteristics specified in claim 1.
- the system according to the invention enables, with minimal energy consumption, the generation of a periodic load with which a rod clamped at one end is loaded so that this rod vibrates.
- the frequency of the periodic loading with which the rod clamped at one end is loaded and the eigenfrequency of the clamped rod are the same, because the aim of applying the periodic loading is precisely to bring the rod clamped at one end into the situation in which the phenomenon of resonance appears.
- it is desirable for the resonance to appear because the system allows control of the phenomenon by limiting the oscillation amplitude and allowing the decrease in kinetic energy as a result of the increase in the amplitude of oscillation caused by the resonance is stored in the rod.
- the rod clamped at one end In order to bring the rod clamped at one end to vibrate, it is triggered with a frequency equal to the natural frequency, for example by using at least one working cylinder, its The shaft is periodically driven by the thrust of a pressurized fluid applied to it.
- the pressurized fluid is in turn, by means of appropriate control over a pair of electrovalves, periodically fed to the working cylinder and precisely at a frequency that is equal to the natural frequency, so that the rod of the shaft of the at least one working cylinder per second Painting is triggered which is equal to the value of the natural frequency of the rod.
- conversion and transmission means and drive means are provided.
- the conversion and transmission means convert the vibratory movement of the rod into a back and forth Fiertranslati onsterrorism and then transfer this back and forth movement to the drive means, which thereby perform a cyclic drive movement.
- the drive means drive a device for generating electrical energy to which they are connected so that it generates the electrical energy.
- Two different technical solutions are provided, depending on whether the device for generating electrical energy is an alternating current generator (see claim 10) or a linear generator (see claim 11).
- the working cylinder is arranged in such a way that (see claim 2) the point at which the rod is hit by the shaft of the working cylinder is as close as possible to the clamped rod end. This has the effect that the stroke of the shaft when it is extended is minimal and therefore the energy consumption required to extend the shaft is minimal.
- a measuring device of the oscillation amplitude and the frequency of the oscillations of the rod clamped at one end can also be used, so that the phenomenon of resonance can be monitored, controlled and maintained over time can, and the pressure of the pressurized fluid increasing pressure increasing device (see claim 6) can be provided.
- the pressure increasing device it is possible to change the pressure value in the plant part, which is arranged downstream of the pressure increasing device increasing the pressure of the pressurized fluid, compared to the plant part arranged upstream of the same as required. Thanks to this device, you can, for example, the upstream of the device to the system part, which is arranged in consideration of a pressure value that is smaller than the pressure value present in the downstream of the device, which results in a cost saving.
- the pressurized fluid is preferably flowing water from an ordinary inlet line of the water line. It is pressurized water that is widely available everywhere.
- the working cylinder is a hydraulic working cylinder (see claims 3 and 4).
- This further working cylinder is located farther away from the clamped rod than the at least one working cylinder (see claim 8), so that the shaft of this further working cylinder strikes the rod at a point at which the rod oscillates with an oscillation width greater than that which is possible in the vicinity of the clamped rod end and this makes it easier to achieve the desired vibration state.
- 1-4 is a three-dimensional overall view of four exemplary embodiments from a first embodiment of the system according to the invention, in which the device for generating electrical energy consists of an alternator, but the individual constituent parts of the system are not all shown on the same scale to facilitate understanding;
- 5-8 is a three-dimensional overall representation of four exemplary embodiments from a second embodiment of the system according to the invention, in which the device for generating electrical energy consists of a linear generator, but the individual components of the system are not all shown on the same scale, to facilitate understanding;
- FIGS. 5-8 show a longitudinal section and a cross section of the linear generator shown in FIGS. 5-8. Best way to carry out the invention
- a system for generating electrical energy is Darge presents, in which a rod 1 clamped at one end is made to vibrate and the vibratory movement is used to generate electrical energy.
- a clamped rod 1 forms a vibratory system and has its own so-called natural frequency, which can be calculated in a known manner using the physical and geometric properties of the rod 1.
- the system comprises: a source 2 of a pressurized fluid, an inlet line 3 of the pressurized fluid which is connected 3 to the source 2 of the pressurized fluid, and an inlet electrovalve 4, the inlet opening of which is connected to the feed line 3 is connected.
- the system also comprises a three-way connection piece 5, a drainage valve 6 and a drainage line 7.
- the three-way connector 5 has an inlet opening 5a, an outlet opening 5b and a connection opening 5c.
- the inlet opening 5a of the three-way connection piece 5 is connected to the outlet opening of the inlet electric valve 4 by means of a first intermediate line, while the outlet opening 5b of the three-way connection piece 5 is connected to the inlet opening of the outlet electric valve 6 by means of a second intermediate line.
- the drain opening of the drain valve 6 is connected to the drain line 7.
- the system also includes a connection line 8 and at least one working cylinder 9.
- the connection line 8 is connected to the connection opening 5c of the three-way connector 5 and to the working cylinder 9.
- the fluid flowing from the source 2 can be conducted into the housing 9b of the working cylinder 9 by means of the connection line 8, whereby the shaft 9b of the working cylinder 9 is driven and extended out of the housing 9b of the working cylinder 9.
- the Housing 9b of the working cylinder 9 pushes the shaft 9a against the rod 1.
- these impacts against the rod 1 take place at a frequency which is the natural frequency of the rod 1 is the same.
- the working cylinder 9 is arranged in such a way that the point at which the rod 1 is struck by the shaft 9a is as close as possible to the clamped end of the rod 1, i. in its immediate vicinity.
- the shaft 9a could strike the rod 1 at any point, but the closer this point is to the clamped end of the rod 1, the smaller is the amount of energy that is required for the shaft 9a to strike the rod 1, because all the more so The more this point is close to the clamped end of the rod 1, the smaller the stroke that the shaft 9a has to perform in order to strike against the rod 1.
- the system also includes a control panel 10 by means of which all components of the system and their working positions are operated.
- the pressurized fluid is compressed air and that the working cylinder 9 is a pneumatic working cylinder.
- This solution is certainly suitable for many situations, but since the compressed air is not easily available in large quantities, it is preferred that the working cylinder 9 is a hydraulic working cylinder and that the pressurized fluid is a liquid, in particular pressurized water, is, such as the water from any existing supply line of flowing water of a water line, an industrial plant or an apartment, which in such a case would act as source 2 ..
- the inlet electrovalve 4 and the outlet electrovalve 6 with one of the natural frequency of the rod 1 glei chen frequency of their one first working position, in which the inlet electrovalve 4 is open and the drainage electrovalve 6 is closed at the same time, however, in a second working position , in which the inlet electrovalve 4 is closed and at the same time the drainage electrovalve 6 is open, and vice versa, continuously switched from its said second working position to its said first working position.
- the pressurized fluid flowing from the source 2 can flow to the working cylinder 9 and drive the shaft 9a of the same 9 so that it is extended from the housing 9b of the working cylinder 9. This causes the shock of the shaft 9a against the rod 1.
- the working cylinder 9 is in direct connection with the drain line 7, so that there is a fall in the pressure value of the pressurized fluid, the Pressure value up to the air pressure drops. As a result, a minimal amount of fluid corresponding to the pressure drop simultaneously flows into the drain line 7. As a result, the shaft 9a no longer strikes the rod 1.
- the constant change between the two situations mentioned above i.e. the transition from the first situation to the second, then from the second to the first and then again from the first to the second and so on, causes the shaft 9a to give the rod 1 shocks at a periodic rate.
- n is the natural frequency of the rod 1 clamped at one end
- the inlet electrovalve 4 and the outlet electrovalve 6 are continuously switched over with a frequency equal to the natural frequency n of the rod 1 the inlet electrovalve 4 and the Drain electrovalve 6 n times per second in said first Hästel development, in which the rod 1 is given an impact by the shaft 9a.
- the rod 1, which is struck by the shaft 9a n times per second is subjected to a stress that causes the resonance and the amplitude tends to increase.
- the system also includes conversion and transmission means 11 a, 11 a ‘and drive means 11 b; 11 b ‘.
- the conversion and transmission means 11 a, 11 a ‘convert the oscillating movement carried out by the rod 1 in a back and forth Hertranslationsbe movement and then transfer this back and forth Hertranslationsbewe movement to the drive means 11 b; 11 b ‘continue.
- the conversion and transmission means consist of a first rod 11a, which is connected at its one first end to the rod 1, and a second rod 11a ', which is articulated at its one first end, in particular by a ball joint connected to the second end of the first rod 11a.
- the ball joint that connects the two rods 11 a, 11 a ‘serves to take into account the fact that the free end of the rod 1 also displaces parallel to the longitudinal axis of the rod 1 due to the vibrations.
- the drive means 11 b; 11 b ' are, in particular articulated, connected to the second end of the second rod 11 a' in order to obtain said back and forth translation movement from this 11 a 'and thereby perform a cyclic drive movement.
- a hinge connection may suffice, while in the case of the drive means 11b ', a connection made by a ball joint is preferred, see FIGS. 5-9. In this way it is ensured that the above-mentioned displacements, which the free end of the rod 1 executes parallel to its longitudinal axis, are optimally compensated.
- the system also includes a device for generating electrical energy 11 c; 22. You 11 c; 22 perform two tasks.
- the first task is in counteracting the increase in the oscillation amplitude caused by the resonance in order to keep the value of the oscillation amplitude in a size range that can be tolerated, which corresponds to a decrease in energy, in particular a decrease in kinetic energy, from the oscillating system formed from the rod 1, with others
- the device for generating electrical energy 11 c; 22 also as a device for limiting the amplitude of the vibrations of the rod 1.
- the second task of the device for generating electrical energy 11 c; 22 is to use trainees the kinetic energy that it has taken from the oscillating system formed from the rod 1 in order to generate electrical energy.
- the device for generating electrical energy 11 c; 22 with the drive means to 11 b; 11 b 'connected so that it is driven by the cyclic Antriebsbe movement, the latter 11 b; 11 b '.
- the device 11 c; 22 consists of an alternator 11c in the case of a first embodiment, to which FIGS. 1-4 refer, while it consists of a linear generator 22 in the case of a second embodiment, to which FIGS. 5-10 refer.
- the drive means 11b consist of a drive shaft connected to the rotor of the alternator 11c, and the cyclic drive movement is a rotary movement which is shown in FIGS. 1-4 with a curved arrow.
- the rotor of the alternator 11c rotates, as a result of this rotational movement, around itself within the stator of the alternator 11c and this generates, in a known manner, electrical energy.
- the drive means 11 b ‘consist of the rotor of the linear generator 22 and in this case the cyclic drive movement corresponds to the above-mentioned back and forth translation movement.
- linear generators are known, it has been found useful to show their main features in Figs.
- the linear generator 22 comprises a sleeve 22a which, as shown in FIG. 9, is provided with two openings to allow the passage of the rotor 11b ‘.
- the rotor 11b ' which consists of a number of permanent magnets N (north) and S (south) arranged next to one another as in FIG. 9, coincides with the drive means 11b', so that it can be connected to the second rod 11 a 'is connected, see Figs. 5-10, and a back and forth Hertranslationsbe movement executes.
- the rotor thus goes cyclically into and out of the tubular metal housing 22b, as shown in FIG. 9 with a double arrow, the windings 22c being arranged around the tubular housing.
- the system finally also includes a measuring device 12 of the oscillation amplitude and the frequency of the oscillations of the rod 1, so that the oscillation state can be monitored.
- This measuring device 12 transmits the measurement data to the control panel 10 so that one can monitor the phenomenon of resonance and take all the control measures necessary in time to actively maintain the resonance over time.
- a pressure increasing the pressure of the pressurized fluid is a further component of the system Increasing device 13 which is connected to the connecting line 8 in such a way that it is different from the one in the connecting line 8 flowing and pressurized fluid is flowed through.
- a pressure increasing device 13 can be particularly useful when the pressurized fluid is a gas, e.g. compressed air, in which case the pressure increasing device 13 can be a compressor, or when the source 2 of the pressurized fluid is very remote and therefore it becomes necessary to compensate for any reductions in pressure.
- a pressure increasing device 13 is also useful if you want to increase the pressure value downstream of it 13.
- FIG. 3 relates with regard to the first embodiment and FIG. 7 with regard to the second embodiment
- the system also has a further three-way connector 14, a first 15 and a second locking electrovalve 17, a further connecting line 16 and a further working cylinder 18 comprises.
- the further three-way connection piece 14 has three connection openings 14a, 14b, 14c, two of which 14a, 14b are connected to the connection line 8.
- the two throughflow openings 15a, 15b of the first electro-blocking valve 15 are also connected to the connection line 8, while the two throughflow openings 17a, 17b of the second electro-blocking valve 17 are connected to the further connection line 16.
- the first blocking electrovalve 15 is arranged in the connection line 8
- the second blocking electrovalve 17 is arranged in the further connection line 16.
- the latter 16 is also connected at one of its ends to the connection opening 14c of the further three-way connection piece 14 and at the other of its ends to the further working cylinder 18.
- the shaft 18a of the further working cylinder 18 strikes the rod 1 when it extends out of the housing 18b of the working cylinder 18.
- the first 15 and the second locking electrovalve 17 can by means of the control switchboard 10 of their one first working position in which the first Blocking electrovalve 15 is open and the second blocking electrovalve 17 is closed at the same time, in a second working position in which the first blocking electrovalve 15 is closed and the second blocking electrovalve 17 is open at the same time, and vice versa, from its said second working position to its said first working position, be switched.
- the role of the two locking electrovalves 15, 17 is different from the role of the pair of valves, which is formed from the inlet electrovalve 4 and the outlet control valve 6.
- the role of the two locking electrovalves 15, 17 is namely to connect the three-way connector 5 either with the working cylinder 9 (first working position of the two locking electrovalves 15, 17) or alternatively with the other working cylinder 18 (second working position of the two locking electrovalves 15, 17) connect.
- the two blocking electrovalves 15, 17 have only the task of producing the two alternative ways that connect the three-way connector piece 5 with the working cylinder 9 or with the further working cylinder 18.
- the further working cylinder 18 is arranged such that the distance from the clamped end of the rod 1 at the point at which the rod 1 is hit by the shaft 18a is greater than the corresponding distance at the point at which the rod is 1 is pushed by the shaft 9a of the working cylinder 9.
- the greater distance causes a greater stroke of the extension movement of the shaft 18a, but this greater stroke makes it possible to achieve the resonance in a shorter time.
- the pressurized fluid coming from the source 2 flows to the working cylinder 18 and the further working cylinder 18 can therefore be used to start the method so that the rod 1 begins to vibrate.
- the further working cylinder 18 is shut down by switching the two locking electrovalves 15, 17 from their second working position to their first working position, and the working cylinder 9 is put into operation instead of the further working cylinder 18. Since the stroke of the shock movement of the shaft 9a of the Ulzylin 9 is smaller than that of the shaft 18a of the further working cylinder 18, you can chen and maintain the resonance with a smaller energy consumption.
- FIG. 4 and FIG. 8 refer to a fourth embodiment of the system according to the invention, in which the system also comprises a sealed container 19, a vessel 20 and an electrical cable 21.
- the sealed container 19 is suitable to withstand a pressure higher than the air pressure and is provided with an inlet opening 19a through which the inlet line 3 extends, and an outlet opening 19b through which the outlet line 7 extends. With reference to the vessel 20, this is connected to the drain line 7, while the electrical cable 21 is connected to the alternating current generator 11c or to the linear generator 22.
- the container 19 has a through opening 19c through which the electrical cable 21 extends, by means of which 21 the electrical energy generated by the alternating current generator 11c or the linear generator 22 is transmitted.
- the system according to Fig.4 or Fig.8 is suitable to be immersed in what water, for example in a lake or the sea, so that the lake or the sea serve as the source 2 of the pressurized fluid and it is Pressurized water is the fluid that flows through the feed line 3.
